WRB detail with exterior foam and strapping
I've got 2 layers of 1.5" polyiso with seams taped and staggered. The panels are currently being held up with cap nails and are awaiting strapping @ 16" o.c. My problem is the house wrap and how it fits into my window/R.O. flashing. I've read the article "Where Does the House Wrap Go?" and it says to locate it over the foam (I'll have "outie" windows) and then attach the rainscreen strapping. Do I then hold the WRB OVER the "picture frame" strapping? This would mean that the WRB would be under the strapping in the "field," but then be over the strapping around the window. This seems kind of bizarre to me, but what do I know? This is my first "green" build. And apart from having to think hard about every single detail, it's going great!
Anyway, I think I'll have this nailed if I can figure out what the heck to do with my WRB and rainscreen around the windows.
I'm sure more than one of you have dealt with this. Any ideas?
Thanks in advance.
